MIPD, or Multiple Inheritance and Polymorphic Dispatch, is a term used in computer programming to describe a language feature that allows multiple classes to be inheriting from a single parent class. In other words, MIPD allows for greater flexibility and efficiency in programming as it enables developers to reuse code and avoid repetition. Some synonyms that may be used in place of MIPD include: multiple inheritance, polymorphism, object-oriented programming, and class hierarchies. These terms all refer to aspects of the process and structure of programming that rely on the inheritance and reuse of code in order to enhance the functionality and efficiency of software.
